H4350 is an Extreme series extruded propellant that has been one of our most favorite powders among shooters for decades. Hodgdon has upgraded H4350 during that time by reducing the grains for enhanced metering and making it insensitive to hot and cold conditions.
H4350 is suited for the WSM family of calibers (270, 7mm, 30, 325) and is also used in cartridges such as the 243 Winchester, 6mm Remington, 270 Winchester, 338 Winchester Magnum, and many others. It’s unbeatable for magnums with light- to moderate-weight bullets!
Warning About Smokeless Powder:
- Do not exceed the loads displayed in the reloaders guide.
- Never mix any two powders regardless of type, brand, or source.
- Never substitute any smokeless powder for Black Powder or any Black Powder substitute.
